Hair Growth Supplements vs. Prescription Treatments
The honest answer: it depends on your situation, but here's a practical breakdown:
Supplements That Have Real Evidence
Nutrafol - Probably the most clinically studied OTC option. Works best for hair thinning caused by stress, hormones, or nutritional deficiencies. Many dermatologists actually recommend it.
Viviscal - Has solid clinical trials behind it, particularly for women with thinning hair.
Biotin (standalone) - Only truly effective if you have a biotin deficiency, which is actually uncommon.
When You Likely Need Prescription Treatment
- Genetic hair loss (androgenic alopecia) - Supplements rarely stop this effectively
- Significant or rapid thinning - See a doctor sooner rather than later
- Prescription options worth asking about:
- Minoxidil (also available OTC as Rogaine)
- Finasteride - for men
- Spironolactone - for women
Smart Approach
- See a dermatologist to identify the cause of your hair loss first
- Services like Hims, Hers, or Keeps offer convenient online consultations and prescriptions if access is a barrier
Bottom line: Supplements can help with nutritional/stress-related thinning, but genetic hair loss almost always needs prescription intervention.
